WARNING
●Do not attempt to test the operation of the pre-collision system yourself.
Depending on the objects used for testing (dummies, cardboard objects imitating detectable objects,
etc.), the system may not operate properly, possibly leading to an accident.
■Pre-collision braking
●When the pre-collision braking
function is operating, a large amount of braking force will be applied.
●If the vehicle is stopped by the operation of the pre-collision brak-
ing function, the pre-collision brak- ing function operation will be canceled after approximately 2 sec-
onds. Depress the brake pedal as necessary.
●The pre-collision braking function may not operate if certain opera-tions are performed by the driver. If
the accelerator pedal is being depressed strongly or the steering wheel is being turned, the system
may determine that the driver is tak- ing evasive action and possibly pre-vent the pre-collision braking
function from operating.
●In some situations, while the pre-
collision braking function is operat- ing, operation of the function may be canceled if the accelerator pedal
is depressed strongly or the steer- ing wheel is turned and the system determines that the driver is taking
evasive action.
●If the brake pedal is being
depressed, the system may deter- mine that the driver is taking eva-sive action and possibly delay the
operation timing of the pre-collision braking function.
■Emergency steering assist
●As emergency steering assist oper-ation will be canceled when the sys-
tem determines that lane departure prevention function has been com-pleted.
●Emergency steering assist may not operate or may be cancel in the fol-
lowing cases as the system may determine the driver is taking actions.
• If the accelerator pedal is being depressed strongly, the steering
wheel is being operated sharply, the brake pedal is being depressed or the driver is giving turn signal. In
this case the system may deter- mine that the driver is taking eva-sive action and the emergency
steering assist may not operate.
• In some situations, while the emer-
gency steering assist is operating, operation of the function may be canceled if the accelerator pedal is
depressed strongly, the steering wheel is operated sharply or the brake pedal is being depressed and
the system determines that the driver is taking evasive action.
• When the emergency steering assist is operating, if the steering wheel is held firmly or is operated in
the opposite direction to that which the system is generating torque, the function may be canceled.
■When to disable the pre-colli-sion system
In the following situations, disable the system, as it may not operate prop-erly, possibly leading to an accident
resulting in death or serious injury:
●When the vehicle is being towed
●When your vehicle is towing another vehicle

●Pre-collision braking
If either of the following occur while the pre-collision braking function is operating, it
will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.
●Emergency steering assist
When the turn signals are flashing, emergency steering assist will not operate in
case of an emergency.
If either of the following occur while the emergency steering assist function is operat-
ing, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.
• The brake pedal is depressed.
●Intersection right/left turn assistance (pre-collision warning)
When the turn signal is not operating, support for turning left or right at an intersec-
tion which targets oncoming vehicles does not work.

LTA (Lane Tracing
Assist)
*
When driving on highways and
freeways with white (yellow)
lane lines, this function alerts
the driver when the vehicle
might depart from its lane or
course
* and provides assis-
tance by operating the steering
wheel to keep the vehicle in its
lane or course
*. Furthermore,
the system provides steering
assistance when dynamic
radar cruise control is operat-
ing to keep the vehicle in its
lane.
The LTA system recognizes
white (yellow) lane lines or a
course
* using the front cam-
era. Additionally, it detects pre-
ceding vehicles using the front
camera and radar.
*: Boundary between asphalt and the
side of the road, such as grass,

WARNING
■Before using LTA system
●Do not rely solely upon the LTA sys-
tem. The LTA system does not automatically drive the vehicle or reduce the amount of attention that
must be paid to the area in front of the vehicle. The driver must always assume full responsibility for driving
safely by paying careful attention to the surrounding conditions and operating the steering wheel to cor-
rect the path of the vehicle. Also, the driver must take adequate breaks when fatigued, such as from
driving for a long period of time.
●Failure to perform appropriate driv-
ing operations and pay careful attention may lead to an accident, resulting in death or serious injury.
●When not using the LTA system, use the LTA switch to turn the sys-
tem off.
■Situations unsuitable for LTA
system
In the following situations, use the LTA switch to turn the system off. Fail-
ure to do so may lead to an accident, resulting in death or serious injury.
●Vehicle is driven on a road surface which is slippery due to rainy weather, fallen snow, freezing, etc.
●Vehicle is driven on a snow-cov-ered road.
●White (yellow) lines are difficult to see due to rain, snow, fog, dust,
etc.
●Vehicle is driven in a temporary
lane or restricted lane due to con- struction work.
●Vehicle is driven in a construction zone.
●A spare tire, tire chains, etc., are equipped.
●When the tires have been exces-sively worn, or when the tire infla-tion pressure is low.
●When tires of a size other than specified are installed.
●Vehicle is driven in traffic lanes other than that highways and free-
ways.
●When your vehicle is towing a
trailer or during emergency towing
■Preventing LTA system malfunc-
tions and operations performed by mistake
●Do not modify the headlights or
place stickers, etc., on the surface of the lights.
●Do not modify the suspension, etc. If the suspension, etc., needs to be replaced, contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Do not install or place anything on the hood or grille. Also, do not install a grille guard (bull bars, kan-
garoo bar, etc.).
●If your windshield needs repairs,
contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■Conditions in which functions may not operate properly
In the following situations, the func- tions may not operate properly and the vehicle may depart from its lane.
Drive safely by always paying careful attention to your surroundings and operate the steering wheel to correct
the path of the vehicle without relying solely on the functions.
